CityVille Bridge Upgrades: Everything you need to know

Last year, CityVille players were given a chance to expand their cities across the river via the introduction of a bridge. Now, that bridge feature comes back to the forefront of the game via three upgrades that you can now complete for your bridge. These upgrades are rolling out slowly, but when they arrive in your game, you'll need to collect various building materials to actually complete them. Zynga says that you'll be able to increase your town's population via these upgrades, so let's take a look at what's required for all three.

Level 2: Activated by clicking on your Bridge after this update has rolled out to you.

6 Expansion Joints

6 Orange Paint

6 Cranes

6 Metal Floor Beams

6 Bridge Towers

You can ask your friends to send you these items via a combination of general news posts and individual requests, or you can purchase them all for City Cash (96 City Cash, to be exact). Reaching each upgrade level (including this one) will change the appearance of the bridge (it will start to look more complex).
Level 3:

10 Oxygen Tank

10 Bridge Barriers

10 Suspension Cables

10 Pylons

10 Bridge Deck Formworks

Level 4:

14 Cutting Torches

14 Construction Signs

14 Wet Suits

14 Heavy Duty Carabiners

14 Bridge Foundations

There will likely be goals associated with updating the bridge as well, and we'll make sure to bring you complete coverage of them, if and when they are released. As for right now, we're all in a waiting game, as we wait for these bridge upgrades to rollout to all users in full.

What do you think of the ability to upgrade your Bridge? Will you start on it right away, or did the initial construction of the bridge take far too long in itself, to want to jump back in? Sound off in the comments.
